    In theory; in practice we have no access to documentation. See above...

    That makes Transmeta part of the _old_ industry :)

    I believe present Transmeta CPUs are quite specialised for x86
    behaviour (memory model etc.) anyway. When you're running on a CPU
    like that, there's probably little to be gained from changing to a
    different front-end instruction set.

    Special tricks like non-cache-ping-ponging locks and faster interrupt
    handling might improve performance, but probably require a change of
    the hardware to implement.
